WHISKING-IVIACI-IIN E.

To all whom t may concern:

Be it known that I, WILHELM IVENK, of Olten, Switzerland, manufacturer,have in vented new and useful Improvements in Vhisking-Machines, ofwhich the following is a specification.

This invention relates to a whisking machine in which the whisk, on therotation of the pan, describes a path similar to that which a whisksuitably operated by hand describes. Similar-appliances in which the panexecutes a rotary motion on the movement of the whisk, are known.

The novelty of the improved machine consists in the fact that the whiskexecutes a double movement for the attainment of which various means maybe employed.

Compared with the heretofore known constructions of such machines theimproved machine further differs in that the pan is held by adjustablejaws and in such a way moreover that pans of various sizes can beautomatically held by the same aws.

The accompanying illustrative drawings show constructions of machinesembodying this invention.

Figure 1 is a side view partially in section showing one suchconstruction. Fig. 2

is a front view. Fig. 3 shows a modified form of construction. Figs. 4to 6 are de- Itail views of parts shown in section. Figs.

7 and 8 are similar views to Figs. l and 2 illustrating anotherconstruction of the improved machine. Figs. 9, 10 and 11 illustratefurther details. Figs. 12 and 13 are also similar views to Figs. 1 and 2showing another construction of machine and Figs. 14 and l5 eachillustrate yet other construe tions.

The whisk 1 is attached to one arm 2 of a bell crank lever 2-6 which ispivotally mounted upon a pin 4. The pin 4 is horizontally arranged andis pivotally mounted in the standard 5 of the machine. The end oftheother arm 6 of the bell-crank lever is sphericalV in form and ispivotally arranged in a bearing 8 Fig. 6, which is movable in thedirection of its length in a disk 9. The disk 9 is attached to avertical shaft l0 which is carried in a bearing 1l on the standard 5 andis driven from a driving pulley 13 by means of a belt 14 and belt pulley15. The pulley 13 is driven at any Specification of Letters Patent.

desired speed from a counter shaft 19 through friction wheels 16 and 17one of which is adjustable.

20 is the machine pan which is rotated by means of a worm and worm wheelfrom the shaft 21. This pan is interchangeable and is held by two jaws22 which are mounted to rotate about a piece 23 which is pivotallymounted on the standard 5. Each jaw 22 is rigidly connected to levers 24which engage slots in a disk 26 that is pivotally arranged on thebearing piece 23 and can be rotated thereon by means of a hand lever.The slots 25 are so arranged that when the disk 26 is moved the jaws areswung outwardly and between the bearing piece 23 and the disk 28 isplaced a torsion spring 29 which tends to move the disk in such a waythat the jaws are pressed against the pan.

V To move the bearing 8 in a radial direction an arrangement like thatshown in Fig. 6 for example may be used. In the disk 9 is formed a slot30 in which the bearing can be moved by means of a screw 31 and nut 32.The nut 32 is prevented from moving axially and is easily accessiblefrom the exterior of the disk. Instead of this arrangement anarrangement like that shown in Fig. 11 may be used. In this constructionthe bearing is formed in a segment 34 which is mounted to rotate upon apin 35 on the disk. The segment is moved by a screw 37 which isprevented from moving axially and can be actuated from the exterior ofthe disk.

The attachment of the whisk to the lever is preferably effected by meansof the appliance shown in Figs. 4 and 5.

The stem 40 of the whisk is movable in the eye 41 of a bolt 42 which ispivotally mounted in a sleeve 43 provided on the arm 2 of the lever 2k6.The sleeve 43 is movable on such lever and can be clamped fast thereonin such way that the stem 40 is simultaneously clamped fast relativelyto the bearing piece 44 which is rotatably arranged upon the sleeve. Thewhisk can 'accordingly be set in various oblique positions by means of asingle lever.

Fig. 3 shows another construction in which the lever 2 6 carrying thewhisk is a straight one and is arranged approximately vertical so thatthe curve followed by the whisk is approximately horizontal indirection, in this arrangement.v Y Y In the construction shown in Figs.7 and 8 the'lever 50 carrying the whisk is arranged to rotate verticallyupon a pin 51 and is driven from a disk 53 which is fixed upon ahorizontal shaft. The disk 53 is driven by means of a belt 54 andstepped pulleys 55, 56 from a Vshaft 57 which also drives the bearingpiece 60 carrying the jaws 58, 59 so that the pan is carried along withit. The pan can be heated by a heating pipe v62. By the rotation of thedisk 55the whisk receives a double movement, which corresponds to thatof a whisk when suitably moved byhand. As the pan rotates continuouslyduring this movement of the whisk the entire contents of the pan areoperated upon uniformly.

The machine may be provided with a clutch adapted to be thrown out ofaction and the driving may likewise be effected by electric motor ifdesired. i

In the construction shown in Figs. 12 and 13 the lever 65 carrying thewhisk is mounted to rotate horizontally upon a pin 66 and is driven froma horizontal disk 67 which at the Asame time is constructed as afriction disk and is mounted directly over the friction wheel 68 o n theshaft 70 driven by the belt pulley 69. The pan 71 is driven by means ofa worm and worm wheel from the shaft 72 which is driven from the shaft70.

In the construction shown in Fig. 14 a bell crank lever 73 carrying thewhisk is arranged to rotate horizontally upon a pin 74 and the other,spherically shaped end, of the bell crank lever 73 is pivotally mountedin a horizontal disk 75 which is driven from a shaft 76 upon which afriction wheel 77 is arranged to move axially. The movement of thefriction wheel is eected by means of a fork 78 which is mounted on aspindle 79 that is pivotally mounted in a support 80. On the upper endof the spindle 79 is keyed a hand wheel 81 by the rotation of which thefork 78 and with it the fricf tion wheel 77 can be adjusted in anydesired manner. The friction wheel 77 is driven from the friction disk82, which is at the same time made in the form of a belt pulley.

In Fig. 15 a bell crank lever 83 carrying the whisk is arranged torotate upon a horizontal pin 84, while the spherically shaped end of thebell-crank lever 83 is pivotally mounted in a disk 85 inclined to thehorizont-al. rIhe disk 85 is fixed upon a shaft 86 inclined to thevertical and which is mounted in a bearing 87 on the machine standard 88and driven from a disk 89 by means of a belt 90 and pulley 91.
